The selling price will be $192
$120 x 60% = $72 markup
$120 + $72 = $192
Answer:
4
Step-by-step explanation:
Since the base angles are the same, the side have to be the same
ML = MN
4x = x+3
Subtract x from each side
4x-x = x+3-x
3x= 3
Divide by 3
3x/3 = 3/3
x = 1
We want the length of MN
MN = x+3 = 1+3 = 4
35x50=1,750-1,600=150. We need to find out what 150 is of 1,600.
150/1,600=?/100
1,600 divided by 100=16
do the same for 150
150 divided by 16=9.375
(you can make it whole if you want)
the answer is about 9%
Answer:
0.67 cm/s
Step-by-step explanation:
The area of a square is given by :
....(1)
Where
x is the side of a square

Differentiating equation (1) wrt t.

When A = 81cm², the side of the square, x = 9 cm
Put all the values,

So, the length of the side of a square is changing at the rate of 0.67 cm/s.
